We are about to finish with the second unit in our Math series. Monday's math included subtracting with the Trade Method. It is the same method that you probably used when you were in math class. Get ready for Tuesday's math however! It is called the partial difference way to subtract. Your child should be able to help you learn this way.
Here is a quick lesson! 459

_______
We will subtract from left to right.
New and different way to think
about math problem solving. 400-100 = 300
50-80 = -30
9-4 = 5
Here's how you think of this: 300 plus a (- 30) = 270 Now add 5 = 275
